Huawei routing

1. Forwarding process from source host to destination host

Router, a device that can forward packets to the correct destination and choose the best path in the forwarding process

Forward data according to the routing table

2. Routing table

A collection of route entries maintained in a router

The router chooses the path according to the routing table

3. The formation of routing table

(1) directly connected network segment

Configure IP address, port up status to form a directly connected route

(2) non-directly connected segments

4. Static routing

Manually configured by the administrator and one-way

Lack of flexibility

5. Default route

When the router cannot find a routing entry for the destination network in the routing table, the router forwards the request to the default routing interface

The encapsulation process of routed forwarding packets

Comparison between switching and routing

1. Routing works at the network layer

(1) forward data according to the "routing table"

(2) routing

(3) routing forwarding

2. Switching works at the data link layer.

(1) forward data according to "MAC address Table"

(2) hardware forwarding

Experimental environment

The three routers are connected to each other, and each router is equipped with an Loopback address simulation environment.
